Dysregulated phosphorylation is well-known in cancers, but it has largely been studied in isolation from mutations. Here the authors introduce HotPho, a tool that can discover spatial interactions between phosphosites and mutations, which are associated with activating mutation and genetic dependencies in cancer.

The authors develop a platform (SATORI) that enables accurate and rapid detection of single-stranded RNA at a single-molecule level without a pre-amplification step. As a proof-of-concept, they demonstrate its utility in detecting the SARS-CoV-2 N gene at a minimum concentration of ~5 fM, which is much lower than other amplification-free CRISPR-Cas-based methods.
